16 Claims.

The object of the present invention is to provide a railroad crossingstructure that has peculiarly eflicient Wear and weather-resistingqualities, and involves units or parts which can i be readilymanufactured and easily assembled.

An embodiment of the invention that is at present considered thepreferable one, is illustrated in the accompanying drawings, wherein:--

Figure 4 is a detail sectional view on the line 44 of Figure 1.

In the embodiment disclosed, a section of a standard railway isillustrated, comprising the ties or sleepers 16 supporting the rails1'7. At the crossing the ties have mounted thereon carrier bars. Thesebars are of channeled formation, and as shown, are of two types. Thebars of one set are designated generally by the reference numeral l8,and one is shown in detail in Figures 13, 14 and 15. As therein shown,the bar is of channeled formation, comprising a bottom wall 19 andupstanding side walls 20, the latter having inturned bearing flanges 21.Holes 22 through the central portion of the bottom wall 19, are adaptedto receive spikes 23 or other suitable fasteners by which the bars 18are secured to the ties, these spikes being readily driven andaccessible through the space between the inner edges of the flanges 21.

The said bars 18 are placed on every second tie at the crossing, and onthe intermediate ties are located other carrier bars 24. One of tehsebars is shown in detail in Figures 10, l1 and 12. It is of metalchanneled formation, compris- Q0 ing a top wall 25 and depending sidewalls 26, the latter having along their lower edges inturned flanges 2'7constitutin the supporting feet. The top wall 25 has upset from thematerial thereof sets of outstanding ears or lips 28, the intermediateportions of which are preferably depressed, as shown at 29. Thesecarrier bars 24 are secured in place by spikes or other fasteners 30driven through openings 31 in the top walls and entering the ties onwhich said carrier'bars 7 are placed.

Supported on the two sets of carrierbars 18 and 24 transversely thereofand therefore longitudinally of the rails and between said rails, arewhat may be termed tread or roadway bars. These are designated generally31. The detail structure of one of these bars is shown in Figures 5, 6and 7. Each is of channel formation and consists of a top or bearingwall 32, which may be suitably roughened on its upper face, as illus- 8trated in part at 33 in Figure 6, and also in Figure '7. Depending fromthe side edges of this top wall 32 are side supporting walls 34terminating at their lower ends in inturned supporting flanges 35 thatconstitute feet which rest upon the bars 18 and 24. It will be noted byreference to Figures 5 and 7 that the flanges 35 are cut away atintervals and as shown at 36, the length of the spaces thereby formedbeing slightly greater than the length of the lips 28 of the supportingbars 24. These lips 28 are elevated sufficiently above the top wall 25of the bars 24 to permit the sections of the flanges 35 to pass beneathsaid lips, as shown in Figure 3.

It will be evident then that if the carrier bars 18 and 24 are securedon the ties 16, the tread bars 31 can be placed side by side thereon,the lips 28 entering through the spaces 36. The tread bars then haveonly to be moved a short distance longitudinally to cause them to beinterlocked 10 or held by said lips 28. A roadway across the spacebetween the rails is thus produced and held assembled.

In order to prevent any low hanging elements of the cars engaging theends of the tread bars and perhaps tearing them loose or otherwiseinjuring the crossing and to prevent any longitudinal displacement ofsaid tread bars, guard plates 37 are located at the ends of thecrossing. These plates are of suitable fiat metal with their main noportions upwardly inclined and having outer horizontal flanges 38 thatrest upon the adjacent tie to which they are fastened by suitable boltsor spikes 39. The upper end portion of each plate has a downturnedflange 40 (see Figure 9), and this flange is provided with outturnedlugs 41 that enter the open ends of the tread bars.

It will be evident that this is a structure that can be made of units offormed metal and that these units may be readily placed in position andassembled into a crossing or like structure. When assembled the partsare all effectively interlocked so that they will retain their position.Being of metal they will withstand weatherconditions and trafiic moresuccessfully than ordinary wood plank or the like usually employed forcrossings.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.
